| 摘 要： | 通过对吕梁林局下李林场封育林区的群落组成和结构特征进行调查和研究，结果表明：封山育林能有效地促进森林植被恢复并保护物种多样性，随着封育年限的增加，植物群落的高度、盖度及物种数均发生了明显变化，尤其是垂直结构；封山育林后的土壤理化性质的分析结果也表明，封育后林下的土壤含水量和腐殖质含量均有明显增加的趋势。

| Abstract: | Communities composition and structure identity of Xiali afforestation area of Lvliang forests Board was surveyed and studied, results showed that： closing hillsides to facilitate could effectively promote the restoration of forest vegetation and protect species diversity, with the increase of fencing years, plant community height, coverage and number of species had changed significantly, especially vertical structure; the physical and chemical properties of the soil were analyzed after closing hillsides to facilitate and the results also showed that： the content of soil moisture and humus had obvious increasing trend after closing hillsides to facilitate. |
